Description

Die Erfindung bezieht sich auf einen Blendenring zur Befestigung an einem selbstschließenden Kraftstoff behälterverschluß.The invention relates to an aperture ring for fastening to a self-closing fuel tank closure.

Ein selbstschließender Kraftstoffbehälterverschluß ist beispielsweise aus der DE-OS 34 06 788 bekannt.A self-closing fuel tank closure is known for example from DE-OS 34 06 788.

Es ist angestrebt, Kraftstoffbehälterverschlüsse, insbesondere selbstschließende Kraftstoffbehälterverschlüsse, so zu dimensionieren, daß eine Zapfpistole nahezu formschlüssig in die Öffnung des Kraftstoffbehälterverschlusses einführbar ist. Eine solche Bauweise ermöglicht eine präzise Führung der Zapfpistole. Es wird somit vermieden, daß die Zapfpistole in ungünstiger Lage in den Kraftstoffbehältereinfüllstutzen eingeführt wird, wodurch häufig lästigerweise die automatische Absperrvorrichtung der Zapfpistole ausgelöst wird. Eine möglichst formschlüssige Anpassung des Kraftstoffbehälterverschlusses an die Zapfpistole ist auch dann angestrebt, wenn das Kraftfahrzeug nur mit bleifreiem Benzin betankt werden darf. Eine Verengung der Einfüllöffnung des Kraftsstoffbehälterverschlusses auf das Durchmessermaß der Zapfpistole verhindert, daß eine Zapfpistole für bleihaltiges Benzin, die üblicherweise einen größeren Durchmesser aufweist, in den selbstschließenden Kraftstoffbehälterverschluß eingeführt werden kann.The aim is to dimension fuel tank closures, in particular self-closing fuel tank closures, in such a way that a fuel nozzle can be inserted almost positively into the opening of the fuel tank closure. Such a design enables the nozzle to be guided precisely. It is thus avoided that the fuel nozzle is inserted into the fuel tank filler neck in an unfavorable position, which often annoyingly triggers the automatic shut-off device of the fuel nozzle. A form-fitting adaptation of the fuel tank closure to the fuel nozzle is also sought if the motor vehicle may only be filled with unleaded petrol. A narrowing of the filler opening of the fuel tank closure to the diameter of the fuel nozzle prevents a fuel nozzle for leaded gasoline, which usually has a larger diameter, from being inserted into the self-closing fuel tank closure.

Anderseits wird jedoch durch den nahezu dichten Sitz der Zapfpistole in der Einfüllöffnung des selbstschließenden Kraftstoffbehälterverschlusses des Abströmen der durch das Einfüllen des Kraftstoffes verdrängten Dämpfe aus dem Tank des Kraftfahrzeuges erschwert. Diese müssen durch den verbleibenden schmalen Ringspalt zwischen Einfüllöffnung und Zapfpistole ins Freie treten. Wegen des verengten Strömungsquerschnittes erreichen sie eine hohe Strömungsgeschwindigkeit und blasen der Person ins Gesicht, die mit dem Einfüllen des Kraftstoffes beschäftig ist. Dieses ist gefährlich und jedenfalls unangenehm.On the other hand, however, the almost tight fit of the fuel nozzle in the filler opening of the self-closing fuel tank closure complicates the outflow of the vapors displaced by the filling of the fuel from the tank of the motor vehicle. These must step outside through the remaining narrow annular gap between the filler opening and the nozzle. Because of the narrow flow cross-section, they reach a high flow rate and blow into the face of the person who is filling the fuel. This is dangerous and at least uncomfortable.

Der Erfindung lieft die Aufgabe zugrunde, einen selbstschließenden Kraftstoffbehälterverschluß derart weiterzubilden, daß auch bei nahezu dicht eingeführter Zapfpistole die aus dem Tank, verdrängten Kraftstoffdämpfe sicher und bequem abgeleitet werden können.The invention has for its object to develop a self-closing fuel tank closure in such a way that the fuel vapors displaced from the tank, can be safely and conveniently discharged even when the fuel nozzle is almost tightly inserted.

Diese Aufgabe ist dadurch gelöst, daß an dem Krafstoffbehälterverschluß ein Blendenring befestigt ist, der ein an den Kraftstoffbehälterverschluß unter Freilassung eines Luftspaltes anschließendes Führungsrohrteil aufweist, das an seiner dem Kraftstoffbehälterverschluß abgewandten Seite in einen umgestülpten Randbereich übergeht.This object is achieved in that a diaphragm ring is attached to the fuel tank closure, which has a guide tube part adjoining the fuel tank closure with the release of an air gap, which passes on its side facing away from the fuel tank closure into an everted edge region.

Durch den Blendenring gemäß der Erfindung, insbesondere durch dessen Führungsrohrteil wird eine sichere Führung der Zapfpistole gewährleistet. Das Führungsrohrteil kann an die Form der Zapfpistole so angepßt sein, daß nur wenige Millimeter Spiel zwischen dem Führungsrohrteil und der eingeführten Zapfpistole bestehen, so daß die Zapfpistole eine definierte Lage einnimmt, die ein störungsfreies Betanken, d.h. eine Betanken ohne zurückspritzenden Kraftstoff und ohne Auslösung des automatischen Abschaltventils, ermöglicht ist. Die infolge des Betankungsvorganges aus dem Kraftstoffbehälter verdrängten Dämpfe können über den Luftspalt ohne daß sich im Innern des Tankes ein allzu großer Überdruck aufbaut, abströmen. Sie werden im Innern des umgestülpten Randbereichs umgelenkt und gleichmäßig nach außen über den vollen Umfang des Blendenringes verteilt, so daß die den Kraftstoffbehälter füllende Person nicht durch die Dämpfe belästigt oder gefährdet wird.The diaphragm ring according to the invention, in particular by its guide tube part, ensures reliable guidance of the nozzle. The guide tube part can be adapted to the shape of the nozzle so that there is only a few millimeters of play between the guide tube part and the inserted nozzle, so that the nozzle takes up a defined position which ensures trouble-free filling, i.e. refueling without fuel splashing back and without triggering the automatic shut-off valve is made possible. The vapors displaced from the fuel tank as a result of the refueling process can flow out through the air gap without excessive excess pressure building up inside the tank. They are deflected inside the upturned edge area and evenly distributed outwards over the full circumference of the aperture ring, so that the person filling the fuel tank is not bothered or endangered by the vapors.

Nach einer besonders vorteilhaften Weiterbildung der Erfindung umschließt der umgestülpte Randbereich die Mündung des Kraftstoffbehälterstutzens unter Freilassung eines Luftspaltes. Bei einem derartig weit umgestülpten Randbereich werden die aus dem Behälter austretenden Kraftstoffdämpfe in ihrer Strömungsrichtung nahezu um 180° umgelenkt und strömen so von der den Kraftstoffbehälter füllenden Person weg. Durch die Umschließung des Randbereichs der Mündung ist der (selbstschließende) Kraftstoffbehälterverschluß vor Manipulationen, insbesondere gegen Diebstahlt geschützt.According to a particularly advantageous development of the invention, the turned-over edge area encloses the mouth of the fuel tank neck, leaving an air gap free. In the case of an edge region that is turned inside out so far, the fuel vapors emerging from the container are deflected in their flow direction by almost 180 ° and thus flow away from the person filling the fuel container. The (self-closing) fuel tank closure is protected against manipulation, in particular against theft, by enclosing the edge region of the mouth.

Durch an der Innenwand des umgestülpten Randbereichs angebrachte Längsstege wird eine besonders gute Formhaltigkeit des Blendenrings erzielt.Longitudinal webs attached to the inner wall of the everted edge region ensure that the diaphragm ring maintains its shape particularly well.

In dem Führungsrohr kann nach einer weiteren vorteilhaften Ausführungsform ein die freie Öffnung des Führungsrohres begrenzender Vorsprung angeordnet sein. Ein solcher Vorsprung ist insbesondere dazu geeignet, die Einführung von bestimmten Zapfpistolen zu verhindern.According to a further advantageous embodiment, a projection delimiting the free opening of the guide tube can be arranged in the guide tube. Such a projection is particularly suitable for preventing the introduction of certain nozzles.

Nach einer vorteilhaften Weiterbildung der Erfindung ist in dem Führungsrohr an seinem dem Kraftstoffbehälterverschluß abgewandten Ende ein wulstförmiger Steg angeordnet. Dieser wulstförmiger Steg kann sich mit einem entsprechenden Vorsprung oder einer Schulter an der Außenwand der Zapfpistole verhaken, so daß die Zapfpistole sich gehalten und ein Herausrutschen aus dem Einfüllstutzen vermieden wird.According to an advantageous development of the invention, a bead-shaped web is arranged in the guide tube at its end facing away from the fuel tank closure. This bead-shaped web can get caught on the outer wall of the nozzle with a corresponding projection or shoulder, so that the nozzle is held and slipping out of the filler neck is avoided.

Gemäß einer weiteren besonders vorteilhaften Ausführungsform der Erfindung ist der Blendenring mit Einrastmitteln versehen, mit denen er auf dem Kraftstoffbehälterverschluß einrastbar ist. Dies ist in fertigungstechnischer Hinsicht besonders vorteilhaft, da durch die Wahl eines entsprechenden Blendenrings derselbe Kraftstoffbehälterverschluß an verschiedene Zapfpistolenformen angepaßt werden kann. Auch können Blendenringe mit zur Längsachse des Einfüllstutzens geneigten Führungsrohren vorgesehen sein, die vorzugsweise bei geneigten Kraftstoffeinfüllstutzen je nach Kraftfahrzeugtyp zum Einsatz kommen. Durch die Wahl des einrastbaren Blendenrings kann somit der Kraftstoffbehälterverschluß in fertigungstechnisch einfacher Weise an den konkreten Bedarfsfall angepaßt werden.According to a further particularly advantageous embodiment of the invention, the diaphragm ring is provided with latching means with which it can be latched onto the fuel tank closure. This is particularly advantageous in terms of production technology, since the same fuel tank closure can be adapted to different fuel nozzle shapes by the selection of an appropriate aperture ring. Orifice rings can also be provided with guide tubes inclined to the longitudinal axis of the filler neck, which are preferably used with inclined fuel filler neck depending on the type of motor vehicle. Through the choice of the snap-on aperture ring, the fuel tank closure can thus be adapted to the specific need in a production-technically simple manner.

Wenn nach einer weiteren vorteilhaften Ausführungsform der Erfindung die Einrastmittel im Innern des umstülpten Randbereichs so angeordnet sind, daß sie bei auf dem Kraftstoffbehälterverschluß eingerastetem Blendenring unzugänglichsind, ist der Blendenring ebenso wie der Kraftstoffbehälterverschluß gegen Diebstahl gesichert. Nach einer weiteren vorteilhaften Ausführungsform bestehen die Einrastmittel aus zwei um 180° versetzt angeordneten, jeweils eine Einkerung aufweisenden Vorsprüngen, in die ein in radialer Richtung vorstehender Rand des Kraftstoffbehälterverschlusses einrastbar ist. Wird der Blendenring bei dieser Ausführungsform auf den Kraftstoffbehälterverschluß aufgedrückt, so wird der durch die auf dem radialen Rand auflaufenden Vorsprünge oval deformiert und der Rand rastet in die Einkerbungen ein, wobei der Blendenring wieder seine ursprünglich runde Form annimmt.If after another advantageous off In the embodiment of the invention, the latching means are arranged in the interior of the everted edge area in such a way that they are inaccessible when the aperture ring is snapped onto the fuel tank closure, the aperture ring is secured against theft, as is the fuel tank closure. According to a further advantageous embodiment, the latching means consist of two projections arranged offset by 180 °, each having a notch, into which an edge of the fuel tank closure protruding in the radial direction can be latched. If the diaphragm ring is pressed onto the fuel tank closure in this embodiment, the protrusion running on the radial edge deforms oval and the edge snaps into the notches, the diaphragm ring again taking on its originally round shape.

Durch mehrere an der Innenwand des umgestülpten Randbereichs angebrachte Axialanschläge kann nach einer weiteren vorteilhaften Ausführungsform eine genau definierte Position des Blendenrings erreicht werden.According to a further advantageous embodiment, a precisely defined position of the diaphragm ring can be achieved by a plurality of axial stops attached to the inner wall of the turned-over edge region.

Griffeinkerbungen an der Außenwand des umgestülpten Randbereichs erleichtern nach einer weiteren vorteilhaften Ausführungsform die Montage des Kraftstoffbehälterverschlusses zusammen mit dem aufgesetzten Blendenring in einem Einfüllstutzen eines Kraftfahrzeuges.According to a further advantageous embodiment, grip notches on the outer wall of the everted edge area facilitate the assembly of the fuel tank closure together with the attached cover ring in a filler neck of a motor vehicle.

Die Erfindung wird nachfolgend anhand der in den Figuren schematisch dargestellten Ausführungsbeispiel näher erläutert. Es zeigt:

  • Figur 1: einen Blendenring gemäß der Erfindung, aufgesetzt auf einen selbstschließenden Kraftstoffbehälterverschluß im Längsschnitt;
  • Figur 2: einen Blendenring mit Kraftstoffbehälterverschluß, montiert im Kraftstoffeinfüllstutzen eines Fahrzeuges. Der Blendenring ist an die Form der üblicherweise für bleifreies Benzin verwendeten Zapfpistolen angepaßt.
The invention is explained in more detail below with reference to the exemplary embodiment shown schematically in the figures. It shows:
  • Figure 1: an aperture ring according to the invention, placed on a self-closing fuel tank closure in longitudinal section;
  • Figure 2: an aperture ring with fuel tank closure, mounted in the fuel filler neck of a vehicle. The aperture ring is adapted to the shape of the nozzle usually used for unleaded petrol.

In Figur 1 ist ein Blendenring I im Axialschnitt zu erkennen. Er weist ein etwa zylinderförmiges Führungsrohr 4 auf, das in einen unter Freilassung eines Ringraumes umgestülpten Randbereich 5 übergeht. Der Randbereich weist in dem an das Führungsrohr anschließenden Teil eine etwa unter 45° zur Längsachse des Führungsrohres 4 verlaufende Schräge 5a auf und geht danach in einen zylindrischen Teil 5b über, der näherungsweise koaxial zu dem Führungsrohr 4 ist. Über einen Zentrumswinkel von 180° weist das Führungsrohr an seinem von dem Einfüllstutzen des Kraftfahrzeuges abweisenden Ende einen Wulst 9 auf, der sich zu seinen Enden hin abflacht. Der Wulst 9 greift hinter einen entsprechenden Vorsprung an der Zapfpistole und sichert diese gegen Herausrutschen. In dem zylindrischen Teil 5b des umgestülpten Randbereichs 5 befinden sich an der Innenseite Längsstege, also Stege, die parallel zur Längsachse des Führungsrohres 4 verlaufen. Diese Stege sind jedoch bei der in Figur 1 gewählten Schnittdarstellung nicht erkennbar. Durch das Anbringen dieser Stege kann selbst bei Wahl einer geringen Wandstärke eine ausreichende Eigensteifigkeit des Blendenringes I erzielt werden. Zwei sich gegenüberliegende Stege sind mit einer Anlauframpe und einer Einkerbung versehen, in die ein radial vorstehender Rand 10 eines Kraftstoffbehälterverschlusses 2 einrastbar ist. Die Axialposition der Einkerbung ist dabei so gewählt, daß in dem eingerasteten Zustand zwischen dem Ende des Führungsrohres 4 und dem Kraftstoffbehälterverschluß 2 ein ringförmiger Luftspalt 3 verbleibt.A diaphragm ring I can be seen in axial section in FIG. It has an approximately cylindrical guide tube 4 which merges into an edge region 5 which is turned inside out leaving an annular space free. In the part adjoining the guide tube, the edge region has an incline 5a running at approximately 45 ° to the longitudinal axis of the guide tube 4 and then merges into a cylindrical part 5b which is approximately coaxial with the guide tube 4. Over a center angle of 180 °, the guide tube has at its end facing away from the filler neck of the motor vehicle a bead 9 which flattens out towards its ends. The bead 9 engages behind a corresponding projection on the nozzle and secures it against slipping out. In the cylindrical part 5b of the turned-over edge region 5 there are longitudinal webs on the inside, that is to say webs which run parallel to the longitudinal axis of the guide tube 4. However, these webs are not recognizable in the sectional illustration chosen in FIG. 1. By attaching these webs, a sufficient inherent rigidity of the diaphragm ring I can be achieved even if a small wall thickness is selected. Two opposing webs are provided with a starting ramp and a notch into which a radially projecting edge 10 of a fuel tank closure 2 can be snapped. The axial position of the notch is chosen so that an annular air gap 3 remains in the locked state between the end of the guide tube 4 and the fuel tank closure 2.

Der radial vorstehende Rand 10 des Kraftstoffbehälterverschlusses 2 liegt auf dem Mündungsrand 6 eines Kraftstoffeinstützens auf. Unterhalb des Randes 10 ist eine Dichtung 11 angeordnet. Am Grund einer umlaufenden Nut 12 am Halse des Kraftstoffbehälterverschlusses ist ein Sperrzahnung angeordnet, auf der sich eine Federzunge (nicht dargestellt) eines Sperringes 13 nach Art eines Richtgesperres abstützt. Der Sperring 13 weist zwei sich gegenüberliegende Vorsprünge 13a und 13b auf. Unter halb des Sperringes 13, d.h. weiter in Richtung auf dem Kraftstofftank zu, weist der Krafstoffeinfüllstutzen zwei sich gegenüberliegende Vorsprünge 14a, b auf.The radially projecting edge 10 of the fuel tank closure 2 lies on the mouth edge 6 of a fuel support. A seal 11 is arranged below the edge 10. At the bottom of a circumferential groove 12 on the neck of the fuel tank closure, a locking toothing is arranged on which a spring tongue (not shown) of a locking ring 13 is supported in the manner of a directional lock. The locking ring 13 has two mutually opposite projections 13a and 13b. Below half of the locking ring 13, i.e. further towards the fuel tank, the fuel filler neck has two opposite projections 14a, b.

Der Kraftstoffbehälterverschluß wird durch ein Klappe 15 verschlossen, die seitlich in einem Gelenk 16 verschwenkbar gelagert ist. Die Klappe liegt mit einer Dichtung 17 an einem konisch ausgebildeten Teil des Halses des Kraftstoffbehälterverschlusses an. Sie ist durch eine Feder 18 in Richtung auf ihre Schließposition vorgespannt.The fuel tank closure is closed by a flap 15 which is pivotally mounted laterally in a joint 16. The flap lies with a seal 17 on a conical part of the neck of the fuel tank closure. It is biased towards its closed position by a spring 18.

In Figur 2 ist eine weitere Ausführungsform eines Blendenrings gezeigt. Der Blendenring der Figur 2 unterscheidet sich vom Blendenring der Figur 1 dadurch, daß er einen Vorsprung 8 aufweist, durch den die freie Öffnung des Fuhrungsrohres 4 begrenzt ist, so daß nur Zapfpistolen mit bestimmter Form (solche für bleifreies Benzin) eingeführt werden können.A further embodiment of an aperture ring is shown in FIG. The aperture ring of Figure 2 differs from the aperture ring of Figure 1 in that it has a projection 8 through which the free opening of the guide tube 4 is limited, so that only nozzles with a certain shape (those for unleaded petrol) can be inserted.

In Figur 2 ist die aus Kraftstoffbehälterverschluß 2 und aufgesetztem Blendenring 1 bestehende Anordnung auf dem Kraftstoffeinfüllstutzen 19 eines Kraftfahrzeuges aufgesetzt. Der Kraftstoffeinfüllstutzen 19 des Kraftfahrzeuges weist an seinem freien Ende einen nach innen umgestülpten Randbereich auf, der an zwei gegenüberliegenden Stellen (nicht darstellt) durchbrochen ist (Innenbajonett oder Innen-Renk-Verschluß). Durch diesen Randbereich sind die beiden Vorsprünge 14a, b des Krafstoffbehälterverschlusses 2 sowie entsprechende Vorsprünge 13a, b des Sperrings 13 eingeführt. Durch eine Rechtsdrehung an dem Blendenring 1, der vorzugsweise an seinem umgestülpten Randbereich 5 erfaßt wird, laufen die Vorsprünge 14a, b an den nach innen weisenden Kanten des umgestülpten Randbereiches des Kraftsstoffeinfüllstutzens auf, wobei der Rand 10 in Richtung auf den Mündungsrand des Kraftstoffeinfüllstutzens unter Deformierung der elastischen Dichtung 11 gepreßt wird, ebenso wie dies beim Aufsetzen eines Tankdeckels auf einen Kraftstoffeinfüllstutzen geschieht. Die Vorsprünge 13a, b des Sperrings 13 werden bei dieser Drehbewegung in den Ausnehmungen des Randbereiches gehalten, so daß der Sperring die Drehbewegung nicht mitmacht und der Kraftstoffbehälterverschluß infolge der Richtgesperrewirkung des Sperrings unlösbar auf dem Kraftstoffeinfüllstutzen befestigt wird.In Figure 2, the arrangement consisting of the fuel tank cap 2 and the cover ring 1 is placed on the fuel filler neck 19 of a motor vehicle. At its free end, the fuel filler neck 19 of the motor vehicle has an inwardly turned edge region which is broken through at two opposite points (not shown) (inner bayonet or inner bayonet lock). The two projections 14a, b of the fuel tank closure 2 and corresponding projections 13a, b of the locking ring 13 are inserted through this edge region. By a right turn on the aperture ring 1, which is preferably detected on its upturned edge region 5, the projections 14a, b run on the inwardly facing edges of the upturned edge region of the fuel filler neck, the edge 10 in the direction of the mouth of the fuel filler neck under deformation the elastic seal 11 is pressed, just as this happens when a fuel cap is placed on a fuel filler neck. The projections 13a, b of the locking ring 13 are held in the recesses of the edge region during this rotary movement, so that the locking ring does not participate in the rotary movement and the fuel tank closure is permanently attached to the fuel filler neck due to the directional locking effect of the locking ring.

Durch das Einführen eines Zapfpistole 20 wird die Klappe 15 gegen die Wirkung der Feder 18 aus ihrer geschlossenen Stellung gedrückt. Wie in Figur 2 zur erkennen ist, sitzt die Zapfpistole 20 nahezu dicht in dem Führungsrohr 4, so daß eine sichere Positionierung der Zapfpistole 20 gewährleistet ist. Die bei der Befüllung des Kraftstofftankes entweichenden Dämpfe können entlang der fett eingezeichneten Pfeile ins Freie austreten.By inserting a nozzle 20, the flap 15 is pressed against the action of the spring 18 from its closed position. As can be seen in Figure 2, the nozzle 20 sits almost tightly in the guide tube 4, so that a safe positioning of the nozzle 20 is ensured. The vapors escaping when the fuel tank is filled can escape outside along the bold arrows.
